Abstract: Eyeglass lens connector with single-operation interchangeable lenses. The configuration enables cutting lenses with the connector body alone mounted to the lens substrate, allowing eyeglasses to be assembled by utilizing the connector after the lens is cut on demand from a customer. The eyeglasses have a lens connector (1) connecting a lens (5) to an insertion piece of a lens connecting member (2), and an insertion hole (10) for the insertion piece (3). A guide groove for guiding a tip of the engagement piece (3) is provided along the opening end (13) of the insertion hole (10). The lens connector (1) is secured to the lens (5) by fastening two protruding fastening pins (32) into fastening holes (29) provided in the lens (5). The lens (5) is connectable to the lens connecting member (2) by squeezing the insertion piece (3) into the insertion hole (10).

Abstract: The present invention relates to a sunglass attachable to a pair of glasses at a later stage, which sunglass is reliably attached to the glasses and in which a sunglass plate is stably held at a flipped position, and also relates to an attachment fitting thereof. The attachment fitting includes a shaft strip, a base, a base contacting strip, an elastic body, and an elastic receiving strip. The base is rotatable with respect to the shaft strip, and the base contacting strip and the elastic receiving strip are fixed so as not to rotate with respect to the shaft strip. With the elastic force of the elastic body, the base contacting strip is pressed towards the base and the base contacting strip and the base are engaged, thus allowing the sunglass plate attached to ends of the shaft strip to be freely raised upwards and lowered downwards and to be freely stopped in stages.

Abstract: A nose pad device constituting glasses for the far-sighted and the near-sighted is constructed of a nose pad and a connection member installed on the nose pad. Upper and lower ends of a vertically extending supporting member are connected with each of upper and lower positions of the rear surface of the pad body. The connection member has an insertion hole through which the supporting member is inserted and slides vertically along the supporting member. The connection member is held at an upper position and a lower position of the supporting member.
